Magnesium is not found as a free element (i.e. magnesium metal) due to its reactivity as an alkaline Earth metal (group II element). It can be separated by the following processes.
1. Pidgeon process
This involves the reduction of magnesium oxide according to the equation:
Si(s) + 2 MgO(s) ↔ SiO2(s) + 2 Mg(g)
The equilibrium position of this reversible reaction is continually shifted to the right for it to be feasible, through applying a large amount of heat and by lowering the concentration of the product through distilling out the magnesium vapor. This process is widely used in China where magnesium is produced on a large scale.
2. Electrolysis of fused (liquid) magnesium chloride
The overall reaction for the electrolytic process is:
MgCl2(l) → Mg(s) + Cl2(g)
At the cathode, the Mg2+
ion gains two electrons and is thereby reduced to magnesium metal:
Cathode: Mg2+
(l) + 2 e− → Mg(s)
it is purified by putting it through a coffee filter
recovering it from sea water and mineral deposits
No element can be separated into simpler materials; the constituent parts of atoms (protons, neutrons, and neutrons) can not constitute stable materials by themselves, but only in combinations with some of the other constituents.
Like many other elements, magnesium can be found in a variety of compounds.
A large region separated by water from other land is called something
The metal "dissolves" vigorously, producing Hydrogen gas which is seen as a fizzing and a magnesium salt is formed also.
This is a chemical change, like any other burning reaction: magnesium is turned into magnesium oxide by burning reaction with oxygen (from air). 2Mg + O2 --> 2MgO
It is separated from YO MAMA
hounestly i have no idea
weinor
it is
It has coal
I don't have a clue.
By ore processes
it has a high density

Most often by fractional distillation.
Magnesium is an abundant element on Earth. Magnesium is not found in a pure form because it bonds with other elements. A process has to be applied to get the Magnesium separated from the other elements.
